Super Jet 6m6 crank in a 701???

[lostcreek21]

I'm replacing my crank seals and I just took the bottom case off and I noticed that my crank has a 6m6 on it........this is my first time taking a 701 apart. Is this the correct crank for this motor?

The guy I bought the ski from told me a shop rebuilt it. Also, it's a wet jet motor

It's fine.

Yes, that is the factory crank for that motor.

Motor started with the 650/6m6 design. Yamaha changed some things going to 701, but you will see many oem parts that are from 6m6 original design and part numbers.
